Front end alignment specs, 67 big car?


I'll be taking my car in for an alignment after the front end rebuild. A shop right down the street will do an old school alignment to what I'd like.

I know I really shouldn't pay any heed to the old Bias Ply specs. According to most current wisdom I've read, big fat radial tires, and a need to have the car track straight, corner and actually provide some slight steering feel, pretty much throw the 50 year old big car spec out the window.


So as a starting point, here's what I think might be decent.

                        Camber                      Caster                    Toe-in       
 
Stock        + 1/4 +/- 1/2 Deg.       +3/4 +/- 1/2 Deg.        1/8 - 1/4 "


New               - 1/2 Deg.               + 1.5 to 2 Deg.           1/16 - 1/8"


Not sure if +2 degrees of caster is even acheivable on these strut rod cars. But I'll try for a decent amount without putting too much deflection in the lower control arm bushing.
Notice how I'd like some negative camber. Why would I ever want the tops of the wheels tilted out (positive)? You want them tilted slightly in, no? They'll tend to tilt slightly straighter when the car has some weight in it anyway.  

Any thoughts from front the end guru's? 

Cheers, Mark

i agree, 2+ neg degrees caster but you are limited by that lwr bushing.
there is room to shim the upper arm to get the 2+ neg
set camber at 0 or close to it.
